Be it known that'l, RICHARD WATKIN, a `citizen of the United States, and a resi dent of the city (of New York, borough Aof Manhattan, inthe county andSitatel ofNew York, have invented a new" andV Improved Stationelndicator, of whichthe following-is afull, clear,` and enact description.V

The object lof the invention is to provide a new and improved ,station indicator ,more especially designed for use incars to display to the lpassengers"the next*stati`on',land 4arranged to workproperly ongboth tlieoutgoing and return trips ofthe car; j

In order to accomplish the desired result, use is madey of an endless carrier, `actuating means imparting a stepl by f step `traveling' movement to the said carrier, signs pivoted gagedbythe said lug onlthe forward travel of the carrier to swing the sign frompvertical display position into'. an'upward' nondisplay position.y

A practical embodiment of the invention is represented in L the accompanying :drawings forming a part-v of'this* specification, in

i which similar characters ofureferenceindr cate corresponding parts in all ythe views.

Fig. 5 is a perspective view trunnions of asign.- A l The station indicator is mountedin a suitably constructedfcasing 410, preferably arranged overhead lin the middle of a car, and within this casing 10 lisarranged an endless carrier 11 provided with f signs 12 "adapted to be successivelydisplayed through an VVof one of the opening y1?) formedin'the bottomrM ofthe casing 10.' Each of the signs^12- isprovided on'each' facewithfthe nameof a station,r and as many signsy are'provided 4as there are stations along the route of thecar, but it is ex pressly understood that; only one sign atia time isin vertical or dislilay position and i Specification `of Letters Patent.y Patented; A11 gigi. 1917 Appncatidn ined November s, 191e. sei-iai Nb. 129,301..

extends across the car so" that the name of Y the next'stationvcan'be readily read bypersons ineither end of the car.

The carrier 11 is in the form of endless sprocket chaansl passing around sprocket keo wheels'l 'and 17 having their shafts`18 and i 24 engagingja slot 25 in a bar 26 secured to the ysliding door 27 of the car. When the car is-'going "in one direction the Vpawl 21 is in. active` position while the pawl 22 is thrownlioutror lin'inactive position, as indicated in Fig. 1,'and 'consequently when the door 27 isopened a rockingmotion is given to thelever'23 toA causeV the pawl 21 to turn the ratchet wheel 20y and with it the shaft 18 thus imparting'a traveling `motion to the endless carrier `11. lVhen the door isy closed the lever 23 is returnedand the pawl 21 'glides over the teeth of the ratchet wheel 20.

It is Aunderstood that when the pawl 21 is in use theendless carrier is causedfto travel inzthe `direction of the arrows indicated in Fig. 3. llhen` the car yis on the return trip the pawl 21: is then out of engagement with the, ratchet wheel 20 and the pawl 22 is engagedivith the ratchet wheel so that on the openingand closing of the kdoor 27 the end-f less-carrier is caused to travel in the inverse direction of the arrows indicated in Fig. ItIt is understood that 1 do not limit myself to the means shown and described for imparting an intermittent traveling motion yto the carrier 11, as the same may vary according tothe conditions existing on any particular `line of transportation on which swing by its own weightv downward into verf tical display position. In y'order to swing the sign from the disy la osition u wardlyandforwardly that y p 'y P p 'i to, be. fastened overhead in a caratv the middle thereof ,the casing having an opening is, inthe direction in which the lowerv run of theendless carrier is traveling, the following arrangement Ais made:l The trunnions 30 are provided with lugs 34adapted tofpro'-V ject yinto the pathof arms 35 depending from afiXed member 36 attached to the casing l()y andfextendingat the inside thereof ap- V .proximately at the Vmiddle of the casing. By

f reference to Fig. 4, it ywill be noticed that leo ' Patent when a sign l2 swings into vertical position at'fthe time it yis at the middle of the open f ingf13 then the lugs 34 of this sign are in engagementfwith the lower endsof the arms 3,5, and ywhen the neXt intermittent movement is given to the endless. carrier 11 then the lugs 34 cause/the sign to swing upward and forwardso thatfthe ,free end ofl this sign reaches the beginning ends lof the track rails 33 to travel along the, same with a view ,to support the signin non-display position.

It is understood that during thisy forward ymovement ofthe-carrier 1l lthelugs 34 of the display ,signeventuallypass out yfrom Aunder the arms 35 while the next following sign swings into vertical position, and its lugs'34 engage arms 3:5. It is understood that when the .carrier 11l travels inthe treverse :direction of the arrows shown in Fig. 2 during the return tripk of the car then the signs leave the tracks 33 tofswing successivelyinto .display position and-to be then swung upward and forwardly. into non-display position to engage the tracks`32.

v The station indicator shownand `described is verysimple and durablein construction and is composed of comparatively fewparts not liable to get out of order easily.
